Abstract
A series of field experiments with an instrumented vehicle were conducted to investigate the risk taking behaviour and information seeking behaviour of drivers when approaching and driving through a gap. A driver's eye movement and specifically his temporal looking activities, as well as a secondary task were used to investigate his information seeking activities. A "mean risk score" was defined and used as an indicator of a driver's risk taking behaviour. The effects of gap size, vehicle speed and reward conditions were investigated and the obtained results are discussed.
